    o2 sensor....

    Ok well im replacing my sensors and plugs and was wondering what o2 sensor to get for my exhaust? I was thinking bout getting the NGK because those are compatible with alot of the o2 wideband sensors. Any suggestions?

    don't worry about replacing the rear o2 unles you are gettign a cel.
    it serves absolutely zero purpose in fuel efficiency. its only there for monitering catalytic converter function.

    as for the front.
    replace it with a oem ntk sensor.
    nothing else comes close in precision and durability.

    i reccomend a plug and play sensor, makes it a simple 10 minute affair.
    if you are savvy and you want to save some cash,
    get a universal ntk, and wire it in.

    you could get a bosch, but they don't last.

    yeah, thats pretty much every car.
    if the sensor is after the cat it doesnt do anything except tell you if your cat is bad

    Ya im not even worried about that one. I'm just changing the one before it cause its in very bad condition when i switch it out ill take a picture. It kind looks like it got hit with a hammer, got drug on the ground, got the wires cut, and got spray painted. It looks horrible. I found out that the guy who had it before me bout it as a junk car and fixed it but did a horrible job of it. In the processe of making sure all parts are good now.
